[BUG] Markdown is not correct in the preview (or at least compared to other markdown editors online)

[Haiderahandali]

Expected behaviour

To not a skip a slash and make the comment appears like a comment

Actual behaviour

somehow a slash is being skipped and that line is not correctly preview in the markdown preview panel

Steps to reproduce

Open a code block for any language, hit enter, type some code and then follow that by a comment (double forward slash "//") make sure the last three backtick are on the same line and not on a separate line. Somehow one of the slashes is being skipped. See the attached video. The website I am comparing to is stackedit.io I have tried multiple ones online, most of them seems to not have the behavior I am seeing in QOwnNotes. (Though, to be honest, I am not sure what markdown specs says).

Please note while trying to make a minimal example for this bug, I encountered yet (I believe) two different bugs #2962 #2963 this is why I am not providing a minimal example of it, because I want to separate it from the next two bug reports.

[pbek]

I'll try to reproduce that.

[pbek]

Hah, funny find. Seems like that's the way how the md4c library treats it. I tried to use the latest version, didn't help.

But in the end, what you did is not valid Markdown, so the result can be pretty undetermined. ️🤷🏻

[pbek]

Ah, that's even from the code highlighting @Waqar144 added, the md4c library doesn't support highlighting of code.

[Haiderahandali]

So, the problem was not hitting enter?

[pbek]

Exactly

[Haiderahandali]

I still feel it should not be like this, skipping and escape characters, IDK I feel like in some edge cases you will have: while(token.type != '//') token = token.next or something like that down in the parsing code, and that will lead to infinite loop or the like ( on large files) because you keep looking for the next token and it is never there. But if you think you don't need to handle those cases, then I will close the issue, as after all, you said many the main md4c don't handle it.

[pbek]

It's very complex code in https://github.com/pbek/QOwnNotes/blob/6824b56f22f7b0a44bac58896a81ed5fc5f02f3c/src/helpers/codetohtmlconverter.cpp, @Waqar144 did it. Maybe he wants to help out? 😉
